Significance StatementIgA nephropathy (IgAN) is associated with mesangial deposition of aberrantly glycosylated IgA1 containing ? light chains and the association of upper respiratory or digestive tract infection with macroscopic hematuria. We found that peripheral blood Gd-IgA1(+) cells from IgAN patients express predominantly ? light chains and CCR9 and CCR10, compared with healthy controls. Furthermore, Gd-IgA1(+) cell populations in peripheral blood are enriched with plasmablasts/plasma cells. Therefore, IgAN is associated with an increased number of migratory Gd-IgA1-?(+) cells predestined for homing to upper respiratory and digestive tract mucosal tissues, where their final maturation and Gd-IgA1-? secretion may be stimulated during upper respiratory or digestive tract infections.
